Number Three!
This one was a bit of a challenge because I went over 300 tris, then had to do some deletion of hidden faces to be able to add a bit more detail in places. I think there are some n-gons in there, leading to a few shading issues, but I just didn't know how to fix them and stay at 300 tris. Also not sure what is up with the shading on the legs. But hey, this is essentially what I was going for!
